Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Alligatoring is a specific defect observed in the rolling process, particularly during hot rolling.
It refers to the splitting of the rolled metal along a horizontal plane during the rolling operation, resembling the open mouth of an alligator.
This defect usually results from non-uniform deformation, improper rolling temperature, or the presence of brittle phases.
Flash is associated with forging, surface porosity typically originates from casting, and wrinkling is a defect seen in sheet metal forming.
